How to quickly access user id information

[Migrated From Jforum.net]

I am modifying the code to serve our private need - showing additional information on variable pages. In order to query the additional data, I need to have the user id in many places (among source code) in order to query the variable database tables.

In current implementation, user id is not always passed to various commands as an argument. I am still not familiar to the source code structure of this application.

Is there a right place where I can keep it?

Could any one of you suggest an elegant way to keep the session user id and can be retrieved easily?

Thanks in advance!

Just call

int userId = SessionFacade.getUserSession().getUserId();

Many thanks. This is what I need!

One more question:

Is there any handy class and method I can use to quickly check in which groups a given user is?

Do a userDao.selectById() and call getGroups(). That should give your the list.
